Removing a DLB from the Controller
The following actions will cause the DLB to be removed from the controller. If the DLB is executing, it
will be stopped before being removed.
▪
Removing the DLB from the controller through the Online Operations menu.
▪
Programmer connection to controller is lost by going offline or a communication failure that
causes a DLB Heartbeat timeout
▪
Switching from programmer mode to monitor mode
▪
Downloading to controller (Config, Logic, Stored Values, etc.)
Clearing the controller, other than fault tables and controller supplemental files
▪
▪
Performing any Flash operation, other than Verify
▪
Uploading from controller (Config, Logic, Stored Values, etc.)
▪
Changing the DLB that is on the controller
If there is an executing DLB, and you transition from RUN Mode to STOP Mode, the executing DLB will
be stopped as well. The DLB will not be removed from the controller in this case.
If you initiate an upload, and there is a DLB on the controller, you will be prompted for confirmation
and notified that the DLB will be removed and that all active DLBs will be made inactive. If there are
no DLBs on the controller but there is at least one active DLB, you will be prompted for confirmation
and notified that all active DLBs will be made inactive. If you choose to abort the upload, no changes
are made. If you proceed, all DLBs are deactivated. If DLBs are de-activated, you will have to
reactivate them manually.
When a DLB is removed from the controller, any PMM data logger (DLOG) and event queue (ELOG)
files that were created by the DLB are also removed.
Basic Steps for Using a DLB in the Controller
1) Create an LD Block under the Active Blocks DLB Node in the Navigator.
You can accomplish this in several ways, such as by creating a new block under the Active Blocks
node, dragging a block from the Toolchest, or copying and pasting a block from another project.
2) Select DLB block properties, for example, Execution Mode, as desired.
3) If necessary, change the Target property, DLB Heartbeat. For larger projects, you may need to
increase DLB Heartbeat from its default value of 1000ms to avoid timing out while performing
some operations, such as opening the Controller File Explorer.
4) Go online to the Controller and go into Programmer Mode, Logic Equal.
5) Right click the DLB and select the Online Operations menu to download the DLB to the controller
and start its execution. (To download and start the DLB in one operation, select Online
Operations > Start.)
6) Monitor DLB execution.
